We know the talented lineup of musicians going into the Rock and Roll Hall of Fame as part of the 2013 induction class, and now we have details on a number of special guests that will honor the inductees at the Rock Hall ceremony.

Prog-rock veterans Rush will be inducted by Foo Fighters' Dave Grohl and Taylor Hawkins during the April 18 ceremony. Grohl, in particular, has spoken publicly in the past about his love for Rush and how crucial they were to his teenage years. He told Rolling Stone, "It was, like, woah -- drums! You could be, like, the leader, then take over the world." But as much as he loved Rush, he also says he had to cover his fandom due to their "questionable" cover art. He recalled, "On the back [of the album], they’re all in white silk, one dude is in a kimono, and the other has these gnarly Cameron Diaz disco pants where the seam is perfectly [lined] in the middle of both of his balls. I didn’t tell anybody that I liked this band because of that dude’s f---in’ nuts! I was afraid my friends would beat me up.”

In addition to Grohl and Hawkins, there have been several more confirmed guests as John Mayer and Gary Clark Jr. will perform in honor of blues legend Albert King. Mayer will provide the induction speech. Don Henley has been chosen to induct singer-songwriter Randy Newman. Christina Aguilera and Jennifer Hudson will perform in honor of late disco queen Donna Summer, while Heart and Public Enemy's special guests will be named at a later date.

The ceremony takes place at Los Angeles' Nokia Theatre L.A. Live on April 18. Tickets will be available for the general public via Ticketmaster beginning Feb. 1. A highlights package from the ceremony will air on HBO on May 18.
